Lenovo will use Infineon Technologies OPTIGA Trusted Platform Module (TPM) chips in the new ThinkPad notebooks in an effort to combat security risks. The OPTIGA TPM SLB 9670 chip is designed to increase the data security of laptops and tablet PCs. Sensitive data (e.g., security keys and passwords) can be stored in the TPM chip separately from the main processor. 
According to Infineon, the company also supplies embedded security solutions other companies, including Microsoft, Hewlett Packard, and Samsung. The OPTIGA product family provides different levels of security for products as diverse as multiple-server IT infrastructures and MP3 players.
